Bound Pairs: Direct Evidence for Long-range Attraction between Like-Charged Colloids
B. V. R. Tata, P. S. Mohanty, M. C. Valsakumar
We report observations of stable bound pairs in very dilute deionized aqueous suspensions of highly charged polystyrene colloidal particles, with monovalent counterions, using a co…
Ferromagnetism in cobalt doped n-GaN
S. Dhara, B. Sundaravel, K. G. M. Nair +5
Ferromagnetic ordering is reported in the post-annealed samples of Co doped n-GaN formed by Co+ implantation. A maximum Curie temperature ~ 250K is recorded for the sample with 8 a…
Soft modes and NTE in Zn(CN)2 from Raman spectroscopy and first principles calculations
T. R. Ravindran, A. K. Arora, Sharat Chandra +2
We have studied Zn(CN)2 at high pressure using Raman spectroscopy, and report Gruneisen parameters of the soft phonons. The phonon frequencies and eigen vectors obtained from ab-in…
